Hey everyone, when I start this game, my monitor goes black and pops up "input not supported"... I have a GeForce 6150SE nForce 430 for a video card... any ideas on how I can get things going?

Sounds like the game is trying to use a resolution that the monitor doesn't support. Maybe try editing the file ~/.vendetta/config.ini with a text editor and adjust the resolution to something you know is supported, or maybe switch to windowed mode rather than full-screen (at least until you can sort out a resolution that it will work with). To switch to windowed mode, I think you just find the line that says "windowmode=1" and change it to "windowmode=0". To change the resolution, you'll have to change the xres/yres variables, and also the xsize/ysize variables if they exist.

thanks, this solved the issue for me too
